3 and 3/4
15/4
24/40 ÷ 6/8
Write answer in simplest form for full credit.
4/5
Write .48 as a fraction in simplest form
12/25 <----
24/50
48/100
5 + 3² x (4 - 2) ÷ 2 = ?
14
8+(-11)+(-29)+2-(-5)
-25
8+2+5=15
(-11)+(-29)= -40
40-15=25 ... -25 because -40 is "larger" than +15

2-4+2
-2+2
0
15+(-12)•2+40÷(-8)
-14
15+(-24)+(-5)
15+(-29)
29-15=14 ... -14 because -24 is "larger" than +15
